Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery before performing electrical work.

2. Clean or Replace Air Filter

Locate the air filter housing.
Remove the clips or screws securing the housing.
Take out the air filter and inspect it; replace if dirty or clogged.
Reinstall the housing and secure it properly.

3. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and bore.
Ensure the throttle body opens and closes smoothly.
Reattach the air intake duct securely.

4. Check and Replace Spark Plugs

Remove the ignition coil cover (if applicable).
Using a socket wrench, remove the spark plugs.
Inspect for wear or damage; replace with OEM or equivalent plugs if necessary.
Reinstall the spark plugs and torque to the manufacturer's specifications.

5. Test Fuel System Pressure

Connect a fuel pressure gauge to the fuel rail service port.
Turn the ignition key to the "ON" position (do not start) to check pressure.
Compare readings with manufacturer specifications; replace the fuel filter or pump if out of range.
